Support for other platforms, smartphones
1. Support for other platforms, smartphones
The beta version of the Android client can be downloaded from Google Play (aka Google Market).
Blackberry is not supported currently, and we do not plan its support in the near future.
PSP is not supported currently, and we do not plan its support in the near future.
iPad is supported with the same app you can download from the Apple app store. However, it does not use the native resolution of the iPad.
We do not have a full-featured PC client, but we do have a test client application with command line interface, which can be used from PC.
Please send an email to firstname.lastname@example.org. Please share your ideas on what you would like to use the WiRC for.
Basically you have the following options:
- Write your own client application
- Modify the firmware of the WiRC
The protocol used between the WiRC and the client is open, we send its specification to anyone who requests it (without signing an NDA).
The C source code of a test client application is available too. This test client has command line interface, and can be compiled under Linux.
You must sign an NDA, and we can send you the SDK (build system and the source codes to you).
You should be prepared in C programming in Linux environment to modify the firmware, because an embedded Linux system runs on the 240 MHz ARM CPU of the WiRC.
The maximal WiFi range is between 20 and 50 metres. It might depend on several circumstances like other wireless networks, etc.
WiRC is shipped with USB WiFi dongle without external antenna connector. According to our experiences with external antenna the best case range is still under 100 m. Please see "What type of WiFi sticks are supported?" section if you would like to use a different WiFi dongle.
Yes, in this case you should configure the WiRC to client mode.
By default the WiRC is the Wi-Fi access point, and the smartphone is the client.
If you use an existing network both the WiRC and the smartphone connects to the network, created by a third device (a WiFi router). If you miss-configure the WiFi or the specified network does not exist and you cannot connect to the WiRC any more, use the factory reset file which can be downloaded from http://wirc.dension.com/support
In Access-Point mode the WiRC can create WiFi network with the following types:
- Open network without encrpytion or
- WPA2-AES encrypted network
In Station/Client mode the WiRC can connect to the following network types:
- Open network without encryption
- WPA/WPA2 – TKIP/AES encrypted network
In most cases the connection problems are caused by wiring issues. Please check that not only the power cable is connected to the WiRC, but an ESC (electronic speed controller or BEC) is connected, too, or you supply the right voltage to the system's servo channels (if you use servos please refer to the servos' operating voltage range). For reference please use the wiring diagram in the WiRC manual.
The firmware update is part of the smartphone client application. If the app recognizes a new firmware for the connected WiRC, then the “Firmware upgrade” section is shown in the WiRC menu. If the upgrade is in progress the internal blue LED of the WiRC blinks fast.
Warning: Wait while the internal LED blinks fast and do not disconnect the battery during the update. If you disconnect the battery during the upgrade process, the WiRC may not work any more.
5. Supported devices
If you would like to use multiple cameras (it is possible with a USB HUB) or if you would like to simply replace the camera shipped with the WiRC, please note the following restrictions.
The USB webcam shall support JPEG compression from its hardware and we know that it is not an easy task to find a camera with built-in image compression feature.
The following cameras have been tested:
- Logitech C100
- Logitech C110
- Logitech C170
- Logitech C615
- Logitech C910
The following WiFi sticks have been tested:
- EnGenius EUB9707
- Edimax EW-7711UAn
- TP-Link TL-WN727N (rev 2.3, rev 3.0)
- TP-Link TL-WN7200ND
Please send an email if you would like to use the WiRC with another WiFi dongle as the chipset is important.
We can support Ralink rt2870, rt307x and rt53xx chipsets. You can find a list of the WiFi dongles supported by us on the following page. http://linuxwireless.org/en/users/Drivers/rt2800usb/devices
6. Known bugs
It may occur that you cannot use the 4th digital output as simply as the 1..3 digital outputs as an open-collector output. Unfortunately this is an issue with the 1.4 hardware version of the WiRC. Calculate with a permanent 20 kOhm pull-down when you connect a LED, etc.
